Re: Jbl 2226h and 2447h
I've sent plans to your email address.
The horn you'll need is the Pi Speakers H290C waveguide/horn. It's the only part you can't buy locally because we're the only company that makes it. All the other parts you can purchase anywhere.
You don't h...

Re: Horn loaded Corona Build
Truly excellent.
I hear you about subs that are smaller than the midwoofer in the mains. It just seems "wrong." And you can get higher efficiency from a larger sub, so there's definitely an advantage in using a larger subwoofer.
But the...

Re: My 3π adventure
I agree with you generally about almost everything you said except the part about time alignment. This is impossible in the modal region.
Outdoors, you want sound sources acoustically close together - within 1/4λ of each other - and the electrical si...

Re: Radian 475PB
That's awesome, Bruce! The forward lobe is right where you want it to be! Nulls roughly equally spaced and far apart, outside the vertical beam.
As for the nearby boundaries - side and rear wall - give a helper woofer setup a try. It will provide t...

Re: Low Pass
Changed the setup again.
Pulled the 4 pi's away from the wall and changed the sub crossover from 60 hz to 100 hz. This is Wayne's standard 3 and 4 pi flanking sub setup except my 4's are still on the floor.
Everything is more better. Better bass, t...

Re: Flanking subs
Your flanking subs should work well there. I visualize the mains on stands, toed-in 45°. The flanking subs are just outside, on the floor. Each of the mains and its flanking sub are pushed out nearly to the side wall. This is a good setup. Then put ...

Re: 4PI Plans Request
You've got mail!
I agree with Barry about the JBL 2226H. It is an excellent midwoofer. The flux stabilization ring in the motor structure reduces distortion down to the levels normally only seen in horns. When combined with a horn tweeter, you have...

Re: More on subs
Very good experimentation, and useful information. Thanks for the feedback.
I have almost always found that flanking subs are a first priority, and one or two distributed subs are next in priority. But sometimes the priorities switch - Rooms that ha...

Re: Amp for 4pi speakers
I would describe 100-300Hz as midrange. The fundamentals of human vocals are there; Middle C on the piano is in this range. So it isn't bass at all - It's midrange. And, yes, I think having the speakers on stands will modify the sound in this range. ...

Re: Amp for 4pi speakers
In my experience, 200Hz is about the limit of the flanking sub (helper woofer) approach. But I've blended the woofer with the mid(woofer) to ~250Hz in some loudspeakers and it has worked well.
Some specialized cases, like the constant directivity cor...
